Abstract
An apparatus and a method are described for zero packet loss task migration in an network switch in a computer network. The invention relates to active or programmable networks, i.e. networks based on packet switching algorithms and switch configurations which are subject to change. A well-defined protocol enables an intelligent switch to migrate tasks from one forwarding engine to another without any packet loss. This enables the algorithms and configurations of the switch to be updated or modified arbitrarily.
